How AC1734 actually runs
Pro Flight Search has tracked every published board update for AC1734 across the IAH and YYZ boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 1 completed leg so far: left a little late (~10 min) but landed about 28 min early. Not enough to call it.
The verdict above is that record speaking, so it reflects how AC1734 operates rather than what the timetable promises. Numbers refresh as new flights operate.
